Answer:
49
Step-by-step explanation:
7*7/1=49 This is because 7/1 equals 7 since 1 goes into 7, 7 times so really the equation 7*7 which still equals 49.
Actually the answer is
-3x + 5y = 15
2x + 3y = -10
1/7+2x/3=(15x-3)/21 make all terms have a common denominator of 21
3+14x=15x-3 subtract 3 from both sides
14x=15x-6 subtract 15x from both sides
-x=-6 divide both sides by -1
x=6
*Notice the use of parentheses in this format to make it clear what the numerators and denominators are...
Answer: Graph the integers, then read them from left to right.
I don’t think I need to explain, it’s just common knowledge.
